Chitosan

Chitosan from Zhongbei Northland Bio-chem Industry Co., Ltd is a deacetylated derivative of chitin with purity levels of 85%, 90%, or 95% as specified, identified by CAS number 9012-76-4. The product is supplied in 25kg drums or 20kg cartons, suitable for industrial bulk handling. It is produced through controlled alkaline deacetylation of marine crustacean shells, retaining structural integrity for functional applications.

The material exhibits variable degrees of deacetylation depending on grade, which directly affects its solubility and bioactivity. At 95% purity, it demonstrates stronger antimicrobial and film-forming properties typical of high-grade chitosan used in medical and agricultural applications. Standard industry specifications for chitosan include a viscosity range of 100 to 1000 mPa·s in 1% acetic acid, though this is not confirmed by the supplier. The product is not certified as food or pharmaceutical grade unless explicitly stated.

This chitosan is primarily used in agriculture as a seed treatment and biopesticide that enhances plant defense mechanisms against fungal pathogens. It is also approved for use in hemostatic bandages in the US and EU, leveraging its rapid clotting properties. Buyers in agrochemical, wound care, and transdermal drug delivery sectors source this material. Trade terms are available upon request; standard packaging is 25kg drums or 20kg cartons.
